The High Leverage Network: Enabling a Web 3.0 World David Bishop, Ph.D. LGS CTO October, 2010 LGS Innovations – The Network Experts™ www.lgsinnovations.com Outline High Leverage Network-What is It? Application Innovations Enabling a Web 3.0 World: Network-Aware Application Enablement Content Centric Networking Energy Use in Networks Energy Efficient Routing LGS Proprietary, All Rights Reserved © LGS Innovations, LLC 2010 What is Service Infrastructure? Invent, analyze, and build disruptive technologies – related to distributed communications and computing infrastructures – that provide a superior foundation for advanced networking products and services. Areas traditionally considered to define Service Infrastructure: Application-level protocols (e.g. SIP*, HTTP, SOAP/XML, RTP, RTSP), Communication Architectures and Middleware (e.g. IMS, A-IMS, NGN), Service Infrastructure Applications Network Overlays, Cross-Domain Service Blending, Infrastructure Cloud Computing, Content Distribution & Delivery, Messaging. *Session Initiation Protocol Hypertext Transfer Protocol IP Multimedia Subsystem Networking Realtime Streaming Protocol Realtime Transport Protocol Advanced IMS LGS Proprietary, All Rights Reserved © LGS Innovations, LLC 2010 Next Gen Network Simple Object Access Protocol Extensible Markup Language Towards Network-Aware Application Enablement Disruptive Technologies - Bridging Applications and Network Peer-To-Peer & Cloud Computing Client/Server Strict Separation of ???

LGS Proprietary, All Rights Reserved © LGS Innovations, LLC 2010 Summary and Conclusions The High Leverage Network is the basic strategic direction that ALU has chosen for its future. Networking technologies in support of the HLN are evolving with fundamental new concepts such as CCN. At the end of the day, these may be more important than the physical layer technologies in terms of their impact on the web and how we will communicate using it. Together They are Enabling a World of Ubiquitous Communications Anywhere, Anytime Realize the Dream of Broadband Access to Everyone in an Energy Efficient Way LGS Proprietary, All Rights Reserved © LGS Innovations, LLC 2010
